Nitro cellulose was the main constituent of dynamite (Nitro glycerin & Nitro cellulose) when Nobel invented it. The Nitro cellulose stabilizes the Nitro glycerin so it won't go off spontaneously. But when dynamite gets old it becomes dangerous just like the old film stock. Today, silicon, clay, iron oxide, and alumina is use to stabilize the nitro glycerin. Of course iron oxide, and alumina produces an extremely high temperature reaction when they burn called Thermite.
Ok now you have me concerned – we aren’t talking about the guitar cases here right? You are taking about airtight cases right? I’ve got 50 or so USA made Gibson’s and I leave them in their OHSC. I’ve never had an issue. I do take them out to play – but I don’t get to all of them. I dream of hanging them all on the wall and based on this video you make it sound like that is ideal compared to a case. Do I need to worry? How long does it take for this damage to happen??? Please respond Fran!
There's still at least one company that makes nitrocellulose acetate plastics, but it's a long and tedious process. Some old pens use it, many straight razor handles were made from it, etc. Unfortunately, Fran is incorrect in her belief that it's still very common.
You can get nitrocellulouse lacquer spray, but most 'shiny' finishes are urethane. Other finishes are shellac, not nitrocellulose. The 'Shellac' nail polish? Acrylic.
I think you need a license to buy nitrocellulose lacquer paint nowadays because of the vocs. It's also insanely expensive now. I learned how to paint cars from my dad back in the 70s and 80s.
He was a car re-finisher from the 40s and 50s and worked exclusively with nitro lacquer all the time. Acrylic lacquer has mostly replaced nitrocellulose today for standard finishes. At least for cars anyway.
The most striking fact I remember about nitro cellouose is from the movie projectionists handbook of my grandpa.
There were certain mandatory precaution in piece to keep your cinema from exploding, violently
The same precautions were in place to keep telenovela Tshernobyl from exploding, violently.
Seems legit. For 1930/1940s cinemas.
A few days after watching this, my thumb pick went missing. I have a new bunny rabbits who eats everything she can get in her mouth, and I was irrationally hoping she didn't eat it, and if she did eat it, hoping she wouldn't explode. I did find the pick, ultimately. Thanks, Fran!
At the end of WW2, the Germans hid a lot of films in a bunker. When the Red Army (Russians) opened this bunker forcibly with explosives. Everything ignited Nirto.
That would be Fritz Lang's film Metropolis. This film was previously sold by an American distributor and was cut from 2 1/2 hours to 1 1/4 hours. The original version was considered lost for a long time.
Only the shortened version and fragments of the original existed. In addition the original composition, which didn’t fit the cut film anymore.
A box with original text panels was discovered in Denmark. Until a 16mm copy of the original 32mm movie appeared in Argentina. But this was already in very, very poor quality. However, it was possible to digitize this and thus save it. With fragments from different countries and the shortened version, it was possible to create an original version again.
I noticed that a cat ran through the picture in one copy, but did not appear in other copies.
Obviously the scene had been shot several times and various movie copies were made from it.
The production of the film exceeded all financial means, but today the film is considered to be trend-setting.
Craftsman screwdrivers… the clear handled ones, octagonal in shape, oh man. The plastic started out smelling sweet, but as they age they smell like dirty feet. It's pretty crazy, I don't recall the specific name of the plastic but it's available online. Anyways I love the smell of old furniture as well, just the smell of aged things is wonderful. I even grew up in a house built in the 1860s and the smell from the lumber is… magic.
